CIRCULATION FEATURES OF PRECIPITATION FORMATION IN WINTER IN THE NORTH AND SOUTH OF KAZAKHSTAN IN THE CONDITIONS OF CLIMATE WARMING

Abstract

The article considers the climatic parameters (precipitation and air temperature) that determine snowy and little snowy winters for the period from December to February of 1971 to 2020 years in the south of Kazakhstan. Graphs of the temporal course of atmospheric precipitation and air temperature for the study area were constructed and analyzed. The main statistical characteristics of atmospheric precipitation are calculated. A catalog of major precipitation anomalies (excess, deficit and norm) for the territory of South Kazakhstan has been compiled. A catalog of snowy warm and little snowy cold winters is presented based on the use of the complex criterion W for the study area. The circulation conditions for the formation of snowy and little snowy winters in the south of Kazakhstan are revealed by analyzing the Wangenheim-Girs circulation forms, the North Atlantic Oscillation and Blinova indices.
